To allwhomtmay concern:

Be it known that I, ITam ALFRED DE Pow, a citizen of the United States, residing at Connellsville, in the countyof Fayette `and State of Pennsylvania, have invented a" new. and useful Screening or Separating Machine; and Ido hereby-declare the'followmeans fordi ing t'obe a full,iclear, and exact description a o f the invention, such 'as will enable others skilled in the art to which it appertains vto -make and usetlie same. l

` This invention. relates to an improved screening or separating machine, for screen- -ing or separating ashes, coal and the like,

and one of the objects of the invention istol provide an. apparatus of this lLind havingng the -ashes or coal or the l likeirom a pile, in oo'mbinationwith means provide a porta-le platform or frame, on

for elevating the same to a rotary screening` o'r separatinglcylinder.

A further-'ob'ect of the invention is to which an 'auxiliar frame is pivotally mounted, whereby e auxiliary frame may oscillate, so that the digging means may Vmore convenientlyada t itself for excavating the ashes or the like.

'A further object. ofthe invention is the 'provision' of means for oscillatinglsaid pivotally mounted auxiliary frame.

A further object of the invention is the provision of means for rotating the screening or separating cylinder and thel elevator conveyer. L

A .further object of the invention is the provision of' means adapted be thrown in gear with the screening or separating operating means, whereby the machine` (which is'mounted upon supporting wheels) may be drive'n forwardly.

' In practical ields the details of construction may necessitate alterations falling with- The invention comprises'further features and combination of parts as hereinafter set forth shown in the drawings and claimed.

to 'the drawing 1 designates' a 'suitable 'bedframe whichisprovided a-t the' rear with a'bolster2 'having a rear axle 3, which is provided -with sup porting -wheels 4. 'The forward part foi-the,

hed frame on its `under face is provided' w'ith a bolster 5, tol which an axle bolster 6 is con-v nected in any suitabley manner so as' to turn,

that is;- oscillate, whereby the front supportingwheels 7 (which are carried' by the front axleS, which -is in turn carried by the axle bolster1 l6) may be'turned in one direction or `the -other for steering the 'machine l usuall bars'9 are carried'by the axle'bolster, and in turn support the' tonguel l0, to which a team of draft animals may be connected for drawing the machine from one' place to another. `Svvivellj7 mountedv upon the 'b ed frame, by means of the bolt-,'11 is the lbase 12v of an auxillaryfframe'v 13. By-this conne tion the auxiliary-frame 13 may turn or os ports a pair'of storage and de o'r hoppers 14 and 15, the front andrevar sides 16 of each-of which are inclined downwardly, as shown. The lateral sides -17 of each hopper are perpendicular and are procillate laterally; This auxiliarp frame-supvided with door openings -18 having doors 19 hinged at 20 there'being suitable latches 21 toholdlthey oors closed. The bottom ofV each hopper comprises the inclined pieces 22,l

lwhich are inclined downwardly and later? ally toward the doors, 'so that'material such as ashes or coallthat is screened or separated The vering bins v9c will easily pass out'of the .door opening when the doors are opened. At lthe rear of`v connected by the standar s 25 to the' upper part of the auxiliary frames `13.` The side bars' or members 24 are reinforced relative to the standards 26l ofthe auxiliary framev and its base thereof by means of the braces 27 and 28; -A'suitable digger or .scoop member 29 having teeth30 isprOVided. This conveyer 23 and the=digger or scoopmember or scoop member is providedwith arms 31, 'which are forked as shown at- 32,'sai'd forks being secured at- 33 .to the lower ends of the `theaux'iliary frame an elevating -conveyer l '1s provlded. `This conveyer 23l comprises V the side members 24 havin their upper ends '91451v side bars 'or members 24 of said'conveyer 23.

Mounted in bearings'of the upper and'lower with the-teeth of thevbevel gear 74 of the screening or ,separating drum; A belt 75 ends of the side bars or members are shafts 34 and 35, which have sprockets 36 Aand 37 about which the chains 38 carrying chain 43 travels, which in turn travels about the sprocket44, which is'also carried by the shaft 34. Mounted upon the base of the auxiliary frame is a suitable motor 45, the operating shaft 46 ofwhich-has a pulley 47 on one end. A belt passes about the pul-v ley'47, and is consequently designated by the numeral 48. This belt 48v in turn passes about the pulley 49, which isalso carried by the shaft 41.v Hence when the shaft. -46 -rotates, power is transmit-ted. to the elevating conveyer, by means of ley 49, the sprocket 42 and the chain 43, which operates the sprocket 44. The other end ofthe shaft 46 is provided with a pulley 50, about which a belt 51' passes. A chute 52 is secured at 5 3 on the auxiliary frame 13, and a bracket 54 has arms secured at 56 to the sides of said chute. Formedupon the bracket 54 is a -bearii'ig 55, andv mounted therein and also in bearing 57 ofthe standard 58 is a shaft 59, with which an agitator and screening drum ,60 rotates. This comu bined agitator and screening drum 60 is arranged on an incline and directly overthe hopper 15,. so that the finer parts ofthe ashes or coal, after passing through the wire fabric of the drum (which fabric may be any suitablemesh may deposit in'l the hopper 15, while the arger parts or particles of the/ashes or coal may pass into the hopper 14, there bein a partition 61 between the two hoppers, to eep themate'rial separated. The elevating.conveying buckets as they reach the top ofthe conveyer dump their contents into the chute 52, hence itasses into the screening drum 60 andas be ore'stated the larger mesh passes into the hopper 14 and the finer mesh into'the hopper 15. Mounted in a bearing of the bracket 62 is a shaft 63 having on one end a pulley 64 and on its other end a bevel gear 65.

' Mounted in a bearing 66 of the standard 67 on the top of the forward part'of the auxiliary frame is a shaft 68 which -is also mountv ed in the'bearing 69 of the standard 58, there being collars `70 and 71 on'said shaft 68 to ,prevent axial movement thereof.. On one end of the shaft 68 is a pulley 72 and on its other end a bevel gear 73, which -meshes passes about the pulley 64 and about the pulley 72, so that whenlmotion is imparted the .belt 48, the pullfrom one end of theV bedvv frame.

76 also mounted on the shaft 63) from the `motor pulley 50, power is transmitted to the E as willl be.

agitator and screening drum, clearly apparentresulting from an examination of the drawings. Mountedin a sultable bearing of the bed frame is a perpendicular auxiliary frame maybe oscillated upon its bolt 11, so that the diggeror scoop member may accommodate litself more readily,v to the pile of ashes orv coal, whereby thej digger may more efciently scoop or dig them up.

Mounted in a bearing 82 of the standard 83l is a shaft 84, on one end of which a sprocket -85 is mounted. A sprocket chain 86 passes about the sprocket 85, and in turn about the Y' sprocket 87 on a stub shaft 88 which projects Movable with the sprocket 87 is asprocket 89, and passing about itis a sprocket chain 90, which in turn passes about the sprocket 91, which is rotatable with one of the rear supporting wheels 4 ofthe bed frame. Splined by means of a feather 92 to one end portion of the shaft 84 is a bevel gear 93. A lever 94 is pivoted at '.96 on' the `standard v97 (which rises upwardly 'from the'bed frame), and

has 'one end provided with forks 95, which have slot and pin connections 98 with the hub 99 of the bevel gear 93, so that by grasping the handle 100 of said lever 94, the bevel gear 93 may be moved axially'on the shaft 84 so as to mesh with theA bevel gear L65. Since power is transmitted-.to the gear 65,

motion mayin turn be imparted to the chain- '90 by intermeshing the bevel gears 65 and 93; By this arrangement and operation the apparatus may be moved little by little toward the pile of ashes or coal or the like. The shaft 68 consists of two sections 101 and 102, and their adjacent ends have rectangular portions able sleeve 105 engages. However, the sleeve may be moved axially on the section 101, thereby disconnecting two sections and allowing the seetion 101 to rotate idly.

When' so disconnecting the section 101 and removing the belt 48 from the motor pulley 47, the apparatus may be driven from one place to another by means of the chain drive and the intermeshing of the bevel gears 103 and 104, with which a sutf.

65 and 93. When the two sections 101 and 102 are designed to rotate together, the sleeve 105 may be held to the section 102 by the setbolt 106. In the operation the digger and theelevator which constitute a mecha.- nism for gathering and delivering material to be graded or separated to 'a combined agitator and separating device, are carried upon one end of an auxiliary frame, which'is movable to swing about a vertical axis, there being manual means for swinging or oscillating the movable frame for directing the digger to dilerent places or 'points or a.

dump. rIhe material when. deposited into the combined agitator and separator is agitated and screened into two different grades, which are delivered separably into a pair of storage and delivering bins, which are supported 'upon and movable with the movable frame.- v
